Subject: Replacement of Present 1-ph Ventilation Motor with a New 3-ph Induction

Motor

INTRODUCTION

The purpose of this proposal is to apprise you of the limitation of the present

ventilation system, and to inform you about the benefits of replacing the current

motor. In this report, I first give you a quick gist of the proposal then discuss in detail

the following:

problems relating to the present system A proposed solution to the problem Cost Time Benefits

GIST OF THE PROPOSAL

The problem in the ventilation system was noticed during a routine inspection. I

noticed the following problems with the present system:

1. Insufficient flow of air at the southern end of plant2. Current motor uses too much electricity

These two problems create both unsafe and an inefficient system. However,fortunately, the solution is quite simple and inexpensive. To correct the problem the

present 1-ph motor in the system must be removed and replaced with a new 3-ph

induction motor. This new motor will not only correct the problems of the present

system, it will also yield the following benefits:

1. Increased life span

2. Decreased use of power3.Ability to expand, and4. Minimal installation time

PROBLEMS

Inadequate airflow The main problem with the present system is that it is unable

to generate enough airflow to the southern end of the plant. During my inspection, I

took many different measurements of airflow throughout the plant using an airflow

meter. I observed that the southern end is receiving only 1,700 cubic yards of

ventilation per hour. General standards require that 2,000 cubic yards must be

replaced every hour. If this situation is not rectified, we may be jeopardizing the well-

being of our staff, not to mention a possible penalty from the government. After

closer investigation of the ventilation system, I identified that the only thing wrong

with the system is the motor driving the fan. The motor is badly worn out and

therefore it is unable to generate the necessary flow.

High Energy Consumption The problem with the present system is its

uncommonly high power consumption. I notice this high power consumption while

taking measurements on the present motor with a digital VOM meter. With these

measurements, I calculated that the motor is running at only half its peak efficiency.

An average 3-ph induction motor runs at approximately 90% peak efficiency. Over a

year, the company loses about Rs. 47000 from the inefficiency of the present motor.

SOLUTIONS

If a 3-ph induction motor were installed in place of a 1-ph motor, it would increase

airflow by almost 20%. I calculated this by using the torque and speed features of a 3-

ph motor. This would boost the airflow to the southern end of the plant from 1,700

cubic yards to over 2,000 cubic yards per hour well within the General standards

An average new 3-ph motor can run up to 90% efficiency. An average 1-ph motor of

the same horsepower could achieve only 80% at best. The more efficient a device, the

less costly it is to run.

COST/BUDGET

The overall cost of replacing and installing the new motor should not exceed Rs.2500.

The motor and control together cost Rs. 1300. The wiring would have to be

undertaken by a qualified electrician. The overall labour cost should not exceed Rs.

350. Approximately Rs. 150 will go towards new motor mountings, brackets and the

wire.

TIME

From start to finish, replacement should not take more than 3 hours. It will take

hour to remove the old 1-ph motor, and no more than an hour to install the 3-ph

motor. Clean up work and initial start up of the system takes about 1 and hours.

BENEFITS

Increased lifespan- If a 3-ph induction motor were installed into the ventilation

system, it would provide much longer life than an equivalent 1-ph motor. A 3-ph

motor will last much longer than a 1-ph motor doing the same task. The reason for

this is the simplicity of operation of a 3-ph motor.

Decreased use of powerPower factor is not a clear term used in the description of

any inductive device, including motors. Power factor, if left unattended, alters the

electricity we receive. Although both 1-ph and 3-ph have some power factors

associated with them, a 3-ph motor has fewer. In other words, a 3-ph motor will

reduce the amount we are charged for electrical power.

Ability to expandanother of a 3-ph motor is the expandability we would have in

our ventilation system. With the increase in airflow, we could easily add other

addiction to the ventilation system, with more ease.

CONCLUSION

We must not let this problem continue. A 3-ph motor is the ventilation will best suit

our requirements both for the present and for the future.
